Interesting. Does not very seem relevant, except in special situations, where an attacker can boot the system and can access the console, but cannot change the boot-process or boot image itself. This would immediately exclude any normal PC from consideration, because there, if you can boot, you can also boot something else which gives you the same capabilities (or better) than this exploit. If you can get BIOS access, the same might be possible, so servers with ILO should also not be affected. My take would be that of this vulnerabilituy allowas an attack, then the security model used is broken in the first place. Of course, there are environments that need two (or more) effective security mechanisms, so fixing this is a good idea, but (almost) nobody needs to be very concerned about it.
